DETACEABLE HANDLE FOR LUBRIGATING APPARATUS;

Application filed November 18, 1924. Serial No. 750,604.

This invention aims to provide an improved detachable handle for use with luricant-expelling devices.

In the drawings,which illustrate a preferred embodiment of my invention Figure 1 is a plan View of a lubricantexpelling gun showingthe detachable handle attached thereto;

Fig. 2 is an'end elevation of the parts shown in Fig. l; and V Fig. 3 is a perspective view of the handle detached from the lubricant-expelling gun.

Referring to thedrawings, I have shown a lubricant-expelling gun lhaving a screw threaded stem 2 and the usual handle attached to the stem for rotating the stem relative to the barrel 4 of the gun, thereby to move a piston (not shown) forward or backward in the barrel. With this type of handle, retraction in a direction to retract the piston is a somewhat slow intermittent proc ess and, inasmuch as it must be retracted to permit refilling of the gun, it is advantageous to provide means whereby the stem and piston may be quickly and easily retracted. To this end, I have provided a simple inexpensive detachable handle 5, which may cooperate with the stem and handle of the gun in such a manner continuously and quickly rotated to with draw the piston, the detachable handle removable during the lubricant-expelling operation.

The handle, as illustrated, is provided with a yoke 7 which fits over the stem 2 of the gun to provide a bearing for the detachable handle and a slightly inclined finger 8 for engagement with the handle 3 of the gun, as best illustrated in Figs. 1 and 2. Both the yoke 7 and the finger 8 are pressed from a single sheet of metal which extends in the form of an arm!) beyond the handle 3 of the gun,

the grip 6 of the detachable handle, which r is rotatably mounted thereon so that it may turn relative to the rest of the handle.

In use the yoke 7 of the handle 5 is slipped over the stem 2 of the gun adjacent the handle 3 so that, when the grip 6 of the detachable handle is turned in a contraclockwise direction relative to the gun, the finger 8 will engage the handle 3 of the gun and cause it to rotate in a contraclockwise direction, thereby turning the stem 2 and retracting that the stem may be.

so as to provide a bearing for g the piston. Thus, as illustrated in Fig. 1,

the grip 6 of the detachable handle 5 is 10- While I have shown and described a preferred embodiment of my invention, it will be understood that my invention is best de fined in the following claims.

1. A supplemental handle for a lubricantexpelling gun including quick detachable means comprising a portionfor engagement with the handle and a portion for engagement with the stem of the gun between the handle and barrel thereof, said quick detachable means also including a hand grip generally parallel with the portion for engagement with the handle whereby the stemand handle'of the gun may be continuously rotated in a direction to retract the piston of the gun.

2 A quick detachable handle for a lubrieating gun including a yoke for quick detachable engagement with the stem of the gun beneath the permanent handle of the gun, a finger for engagement with the permanent handle of the gun and a grip operatively connected to said yoke and finger for rotating the stem and handle of the gun.

3. A quick detachable handle comprising an arm portion havingahand grip secured to one end thereof, a U-shapedslot in the other end for receiving the stem of a lubricant-expelling gun and a finger extending from one side of said arm for engagement with thehandle of a lubricant-expelling gun whereby the stem and handle may be rotated at a relatively higher rate of speed.

4. A quick detachable handle comprising a flat arm portion having a rotatable hand slot at the other end for receiving the stem, an ear at each side of said slot for providing relatively wide bearing surfaces for engagement with the stem, and a hook-like finger extending from one side of said arm portion between the hand grip and said ears for engagement with'the handle of the lubricant-expelling gun whereby the handle and stem'may be rotated by rotation of said hand grip aboutthe axis of the stem.

5. A quickdetachable handle for a lubririp secured to one end thereof, a U-shaped' cant expelling gun comprising an armed handle may be rotated continuously at a portion having a hand grip secured to one relatively higher rate of speed, said finger 10 end thereof, a yoke at the other end of the being bent to partially over-lie the handle to arm for receiving the stem of the lubricant further secure the arm in place when in expelling gun and a finger extending from use.
